<\/p>\nStone on one side, timber slats on the other, and a shadow line where they meet: it is one of the most specified feature-wall details in commercial fit-out, and one of the least documented. The reason is that it is not really a stone detail or a timber detail \u2014 it is a junction between two materials with different movement, different tolerance and different trades, and each trade will assume the other has set the datum. This guide sets out what has to be decided before either material goes on the wall: which plane sits forward, how the junction is closed, what happens behind it, and how the fire and moisture strategy survives the meeting point.<\/p>\n
Timber slat panels and flexible stone move for different reasons. Timber takes on and gives up moisture with the room, so a slat array can change width across the seasons, and its fixings have to allow that. Flexible stone is a mineral composite with a fiberglass mesh back; it does not swell with humidity the way timber does, but it is thin enough to telegraph whatever the substrate does beneath it. Put the two hard against each other with a tight butt joint and the gap will either open \u2014 when the timber shrinks \u2014 or crush the slat edges on the dry side.<\/p>\n
There is a second, less obvious cause. Slats are usually built as a framed array with its own substrate, set off the wall by battens. Stone is bonded directly to a flat substrate. The two systems therefore have different finished depths, and the junction is where the depth difference has to be resolved. If that is left to the site, someone forces one material to meet the other, and the result is a taper that runs the length of the wall.<\/p>\n
<\/p>\n
Decide this at design stage, not on site. The common solutions are: stone proud of the slats, so the stone edge casts a shadow onto the timber; slats proud, so the timber array frames and returns over the stone; or both flush with a deliberate shadow gap between them.<\/p>\n
Whichever is chosen, the datum should come from the finished stone face, because flexible stone is thin and cannot be packed out without showing. Set the slat array off the stone, not the other way round.<\/p>\n
Three details cover most situations. A shadow gap is the default: the two materials stop short of each other by a controlled amount, and a dark recess reads as a deliberate line. The gap needs a backer \u2014 a painted or dark-anodised channel \u2014 so that what you see through it is not bare framing, dust and cable. Depth matters more than width here; a shallow wide gap looks like a mistake, a narrow deep one looks drawn.<\/p>\n
Un perfil de trim o revelado es la soluci\u00f3n de respaldo cuando no se puede garantizar una junta de sombra, por ejemplo, cuando el array de listones es instalado por terceros bajo otro cronograma. El perfil absorbe la tolerancia, cubre ambos bordes cortados y aporta a la uni\u00f3n una l\u00ednea definida que no se desplaza. La tercera opci\u00f3n \u2014una junta muy ajustada con sellador\u2014 debe evitarse en cualquier pared de m\u00e1s de unos pocos metros, porque el movimiento no tiene d\u00f3nde ir y la l\u00ednea del sellador se convierte en el defecto visible.<\/p>\n

Aqu\u00ed es donde se concentra la mayor parte del riesgo, y nada de ello resulta visible tras la ejecuci\u00f3n. Tres aspectos deben resolverse antes de instalar cualquiera de los acabados.<\/p>\n
El orden seguro es: primero la piedra, luego los listones. El trabajo de la piedra es h\u00famedo, genera polvo y produce recortes; los listones se rayan con facilidad y sus bordes finos se lastiman. Hacer primero la piedra permite instalar el conjunto de listones en un entorno limpio y acabado, y cerrar la uni\u00f3n una sola vez, sin ocultar da\u00f1os sobre una cara de madera ya terminada.<\/p>\n
Cuando el cronograma obliga a invertir el orden, el conjunto de listones necesita un envoltorio protector temporal y un tope r\u00edgido en su borde, para que el gremio de la piedra tenga un plano de referencia. En cualquier caso, consensuar el datum \u2014una l\u00ednea de tiza o una marca l\u00e1ser sobre la cara acabada de la piedra\u2014 y registrarlo, porque el segundo gremio no estar\u00e1 en obra cuando el primero la deje. Nuestra gu\u00eda de protecci\u00f3n de la piedra flexible instalada durante los trabajos<\/a> aborda el tema de la protecci\u00f3n con detalle.<\/p>\n Stand back three metres and look along the junction. The line should be straight, the gap should be even end to end, and the depth relationship between the two materials should not change across the wall. Then look closely at each end: the termination at a return, a ceiling or a floor is where the tolerance usually shows. A junction that is even in the middle and pinches at the ends was set out from two datums instead of one.<\/p>\n Check the stone edges for chipping where the slats meet them, and check that the shadow gap is actually open \u2014 not filled with adhesive, sealant or dust. A gap that has been bridged to \u201cmake it neat\u201d is no longer doing its job. Finally, confirm the tone of the stone panels at the junction, because a slat array breaks the wall into smaller visual fields and any batch difference becomes more visible against timber than against more stone.<\/p>\n Not as a shortcut. The sheet needs a stable, flat substrate with the right surface for the approved adhesive, and a slat array is neither flat nor stable in that sense. The stone should have its own continuous substrate, with the slat array built independently beside it.<\/p>\n Wide enough to read as a line and narrow enough to look intentional \u2014 the depth is what makes it work. Set it in the detail with the trim or stop that forms it, then hold that dimension along the whole junction rather than adjusting it at each end.<\/p>\n Not if the two are separated. The failure comes from restraining the timber against the stone; a shadow gap or trim gives the movement somewhere to go. The stone itself is dimensionally stable in normal interior conditions, but it is thin and will follow a moving substrate.<\/p>\n No. The classification applies to the stone product, not to the assembly. The timber slats, the cavity and the junction each have their own performance to demonstrate in a fire-rated wall, and the whole build-up needs to be assessed as a system.<\/p>\n For format and thickness options on the stone side, the revestimiento de piedra flexible<\/a> page lists the current range.
